-Using multiple inheritance in GF. AR 15/9/2004.

-The following diagrams show inheritance between abstract syntaxes in two simple systems.

-                   TopCity
-                  /   |    \
-                 /    |     \
-      SystemCity   UserCity  Top
-        /      \   /     \
-  System       City      User

-                  /   |    \

-Idea of each module: 
-
-  User            -- User's moves on any domain
-  System          -- System's moves on any domain
-  Top             -- grammar covering both kinds of moves
-  X = Math, City  -- possible domains
-  UserX           -- User's domain specific moves
-  SystemX         -- System's domain specific moves
-  TopX            -- all moves on the domain X
-
-In parallel to the abstract syntax hierarchies, we have of course
-hierarchies of concrete syntaxes for any language; this directory contains Eng.
